Can not get the picture to come up on cable

unplug tv remove batteries from remote try reset switch on bottom of unit lower left on back

if it was working ok before then ring up and complain and get him back as he did not do the installation properly.

i had the same lines on my 65' mitsubishi tv after replacing the DLP chip. after going back over everything i realized that the casinf that holds the chip in was not in the lock position. i took the chip out and replaced it then turned the little locking mechanism to the locked position. now my screen is perfect. hope this helps.

Tries tv and cable box unplug,replug it back like about an hour later.For the tv to do a resetting itself back to the factory setting.The cable box to reboot and upgraded it software.Than go in to the tv Menu go to Audio Setting go down and do a resetting back to the tv factory setting.By doing these steps u have a great chances to get ur tv audio sound back.Not have the same problems after this than the tv Tuner signal board it is shorted in the audio ICS modjulation sections.Tries websites like Shopjimmy,com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

Unplug,replug an hour later,might reset to factory setting.Tries stop all timer setting.

okay mine just did the same thing.... Same day and all. Let me know if you figure it out and I'll do the same.

have your tv checked by a tech.probably your chip the eprom needs to be reset by lifting it up from the board and resolder back.some one could have put in a code for those channel.good luck.
